The present research explores the relationship between interpersonal insecurity and risk-taking propensity in multiple risk domains and around the globe based on risk-sensitivity theory and research on group identity. In Study 1, participants (N = 209) reported their interpersonal insecurity and risk-taking propensity across seven risk domains. The results show that risk-taking propensity generally increases with interpersonal insecurity. However, this relationship was negative in the cooperation domain and null in the financial domain. In Study 2 (N = 128,162), data from the World Values Survey from 77 countries reveal a positive correlation between risk-taking propensity and interpersonal insecurity with in-group members but a negative relationship between risk-taking propensity and interpersonal insecurity with out-group members %K interpersonal insecurity %K risk-taking %K risk-sensitive theory %K group identity %K domain-specific risk %U https://journals.sagepub.com/doi/full/10.1177/1474704918795520
